Raised floor

ABSTRACT

A raised floor includes a base plate, a raised plate, a support frame, and a transfer structure, in which the raised plate is parallelly disposed above the base plate; the support frame is disposed between the base plate and the raised plate; and the transfer structure that is configured with a first terminal and a second terminal is arranged by fixing the first terminal to the base plat and the second terminal to the raised plate.

FIELD OF THE INVENTION

The present invention relates to a raised floor, and more particularly,to an anti-vibration raised floor.

BACKGROUND OF THE INVENTION

Please refer to FIG. 1, which is a partial sectional view of aconventional raised floor. As shown in FIG. 1, a conventional raisedfloor 900 is substantially a double-layer floor that is formed by havinga raised plate 910 to be disposed above a base plate 920 while allowinga support frame 930 to be sandwiched therebetween for elevated theraised plate 910 above the base plate 920 by a specific height.Generally, the raised plate 910 and the support frame 930 are coupled toeach other by a mean similar to the sleeve joint that can allow the twoto be assembled and dismantled easily.

Conventionally, the fixing of a device 10 to the raised floor 900 isachieved by fixing the stand 11 of the device 10 to the raised plate 910by the use of J-bolts. However, when the raised floor 900 with thedevice 10 mounted thereon is being shaken and vibrated by an externalforce, such as a earthquake, not only the connection between the raisedplate 910 and the support frame 930 can be easily destroyed anddetached, but also the fixing j-bolts 12 can exert certain pulling andtearing forces upon the raised plate 910 and thus damage the raise plate910 if the raise plate 910 is not built strong enough. Consequently, thestability of the device 10 resulting from the fixing of j-bolts 12 onthe raised plate 910 is comprised and thus the device 10 may bedisplaced or even collapse.

Therefore, it is in need of a raised floor capable of overcoming theaforesaid problems.

In this embodiment, the fixing part 144 is made ofa metal.

Please refer to FIG. 4 and FIG. 5, which are a three-dimensional diagramshowing how a structure is being fixedly mounted on a conventionalraised floor, and a three-dimensional diagram showing how a structure isbeing fixedly mounted on a raised floor of the present invention. Thefollowing description relates to how a device that is mounted on araised floor of the present invention can react differently from thesame device that is otherwise mounted on a conventional raised floorwhile being pushed by an external force.

In FIG. 4, the fixing of a device 10 to a conventional raised floor 900can be achieved by fixing the stand 11 of the device 10 to the raisedplate 910 by the use of J-bolts 12. On the other hand, although thefixing of a device 10 to a raised floor 100 of the invention can beachieved similar to that disclosed in FIG. 4, but is different in that:there are transfer structures 140 attached to the bottom frame 13 of thedevice, as shown in FIG. 5. It is noted that the mounting of the device10 can be performed the same as those shown in FIG. 3, and thus will notbe described further therein. As shown in FIG. 5, there are two transferstructures 140 being attached to each of the two short sides L2 whilesimultaneously there are four transfer structures 140 being attached toeach of the two long sides L1.

As shown in FIG. 4 and FIG. 5, the length of the long side L1 of thedevice 10 is 1690 mm, and the short side L2 thereof is 1250 mm, and itsheight L3 is 4180 mm, and weigh 950 kg. In addition, there areaccelerometers being arranged at position A, B, C and F in respective,so as to be used for measuring gravity acceleration variation happeningat those positions.

By exerting a 0.2 g upward pulling force upon the base layers 920 and120 in respectively, the accelerometers that are arranged at position A,B, C and F are enabled to generating a report relating to themeasurement of gravity acceleration variation. Among which, themeasurement from the accelerometer at position A is gravity accelerationvariation in the vertical direction of the raised plate 910 or 110,while the measurements from the accelerometers at position B, C, and Dare the gravity acceleration variation in the X- or Y-direction atdifferent location of the device 10.

Experimentally, there can be seven values obtained respectively atdifferent directions by different accelerometers, which are the sixvalues of gravity acceleration obtained at position B in Y-direction,referring as B-Y, and consequently, at B-X, at B-Y, at C-X, at C-Y, atD-X, and at D-Y, and the one obtained at position A in the verticaldirection, as disclosed in the following table:

Accelerometer position Conventional raised floor Raised floor of theinvention A 0.132 0.060 B-X 0.107 0.094 B-Y 0.084 0.059 C-X 0.105 0.091C-Y 0.081 0.058 D-X 0.110 0.095 D-Y 0.091 0.064

From the above experiment, it is noted that there is a 10%˜40% reductionin gravity acceleration resulting from the raised floor of the presentinvention, comparing with that of the conventional raised floor. Thus,it is clear that the device 10 that is mounted on the raised floor ofthe present invention is able to resist vibrations, such as earthquake,better than the one mounted on conventional raised floor.

To sum up, the raise floor of the present invention is advantageous inthat: it is designed with enhanced anti-vibration ability for preventingany device disposed thereon from tilting over, and also can be alignedand assembled at will to conform to the size and mounting requirement ofa device that is to be disposed thereon, and therefore, the raise floorof the present invention can be for all kinds of machine tables used inphotonic and optoelectronic industry, semiconductor industry, LEDindustry, solar energy industry and even many traditional industries.

With respect to the above description then, it is to be realized thatthe optimum dimensional relationships for the parts of the invention, toinclude variations in size, materials, shape, form, function and mannerof operation, assembly and use, are deemed readily apparent and obviousto one skilled in the art, and all equivalent relationships to thoseillustrated in the drawings and described in the specification areintended to be encompassed by the present invention.
